APPARATUS FOR RAISING GRATES.

Specification forming part of Letters Patent N0. 441,844, dated Novemberl, 1861.

To all whom it may concern:

Be it known that I, ISAAC W. ALLYN, of Philadelphia. Pennsylvania, haveinvented an Improved Device for Raising Stove-Grates; and I do herebydeclare the following to be a full, clear, and exact description of thesame,

eference being bad to the accompanying drawings, and to the letters ofreference marked thereon.

My invention consists in certain devices fully described hereinafter forraising and lowering the grates of stoves and heaters, and t' erebyincreasing or dnninishin g the capacity of the tire place, raisingthe'ignited fuel into close proximity to the culinary vessels, orlowering it when the ovens have to be heated.

in order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation.

On reference tothe accompanying drawings, which form a part of thisspecification, Figure 1 is a sectional view of the fireplace of a stoveor heater, showing my improved device for raising and lowering thegrate. Fig. 2 is a front view, and Fig. 3 a. plan view.

Similar letters refer to similar parts throughout the several views.

A and A are the opposite sides, and B is the back of the fire-place of astove or heater, and on a let ge, a projecting from the sides and backrests the tire-brick lining O. In the front of the fire-place is thevertical grate D, the lower edge of whichis on a line with the top ofthe ledge a. To this ledge a, on each side of the fire-place, are hungtwo cam-shaped levers,

1 and F, to the projecting arms of which ist jointed a bar, G, thelatter being connected by 3 a cross-bar, H, to the bar G, hung to thecamshaped levers on the opposite side of the fireplace. Upon the roundedends of the levers F rests an oblong metal frame I, which fits looselyin the fire place and within this frame is horizontal grate J, the frontend of the grate being supported by a detachable pin, 0, which passesthrough the frame, and the rear end by lugs 61 d, which project from therides of the grate, and rest in suitable depressions in the frame.

When it is desired to have a large fire to heat the oven for baking orsimilar purposes, the horizontal grate I should be brought to theposition shown in the drawings. WVhen, however, it is required torapidly heat the contents of vessels on the stove, or to have the fi1 enear the surface for broiling, the grate J should be elevated by turningthe levers F in the direction of their arrows, anysuitable instrumentbeing applied to the cross-bar H, so as to move the levers in therequired direction.

The ashes may be at any time removed from the fire-place by withdrawingthe pin 0 and allowing the forward end of the grate J to fall.

it will be apparent that a device of the above description is simple andinexpensive; that it can be readily operated and is not liable to becomeclogged by the ashes or rendered unserviceable from the warping of thegrate by heat. It will also be seen that such a device in no mannerinterferes with the operation of the grate when the ashes have to beremoved.

I claim as my invention and desire to secure by Letters PateLt-- Thecam-shaped levers F, hung to the sides of the fireplace and operating onthe horizon tal grate of a stove or range substantially as ISA AC W.ALLYN.
